    Introduction: Virtual reality (VR) is an emerging technological and educational resource that isincreasingly being used in medical education for the development of technical skills through animmersive environment. VR has shown clinical benefits in reducing perioperative anxiety in patientsand also allowing educational experiences to pregrade students on different topics like anatomy andbasic life support training. Even though VR has benefits, adverse effects such as cybersickness havebeen reported, with limited evidence regarding the exposure time for onset and its physiologicalimpact. Measuring and analyzing these parameters is important to establish safe exposure times forVR simulations. Objective: Evaluate changes in heart rate, blood pressure, and cybersicknesssymptoms after a 15-minute exposure to a VR environment (Anatomy and Physiology Lab on METAQuest 2) in pre-graduate medical students, by comparing physiological parameters and applying theSimulator Sickness Questionnaire (SSQ) before and after immersion. Methods: Observational,descriptive, cross-sectional study in which vital signs (heart rate, respiratory rate, and blood pressure)were recorded before and after exposure to a VR environment. The qualitative data were analyzedusing frequencies and percentages, and the quantitative data with medians and ranges. Chi-squareand Student’s t tests were applied to assess differences between time points. Results: No significantchanges were found in heart rate (p = 0.1754). Respiratory rate increased after exposure (p = 0.0017), asdid systolic blood pressure (p = 0.0329), while diastolic pressure remained unchanged (p = 0.7025).Regarding cybersickness, symptoms occurred in 20% of participants, with no association to VRexperience (p > 0.05). Conclusions: VR exposure may increase respiratory rate and systolic bloodpressure without affecting heart rate. Further research is needed to determine optimal immersionduration and predisposing factors that may contribute to adverse effects in order to ensure a safe andeffective immersive experience in medical education.

    Evaluación de software de producción de objetos en Realidad Aumentada con fines educativos
    (Universidad de Murcia, Servicio de Publicaciones, 2019) Cabero Almenara, Julio; Llorente Cejudo, María del Carmen
    El interés del presente artículo está destinado a evaluar las posibilidades que ofrece el software de producción de Realidad Aumentada (RA) existente en el momento actual para su incorporación en el ámbito educativo, con el objeto de identificar aquellas características que se adecuen a las necesidades de los docentes que pretendan diseñarlos, producirlos e incorporarlos a sus aulas. Para ello se construyó un cuestionario destinado a indagar sobre el grado de conocimiento que los expertos que evaluaron los diferentes software poseían de diferentes programas existentes en el mercado para la producción de objetos en RA. Entre los resultados obtenidos, destacar que, ante la falta de estudios que valoren el software de producción de objetos de aprendizaje en RA, el presente trabajo aporta indicaciones, tanto para la selección del mismo, como para tener criterios para su valoración. De las conclusiones obtenidas, destacar que el trabajo ha permitido identificar los diez programas que son más conocidos por los expertos en los momentos en los cuales se realizan, como, por ejemplo: Arlab, Armedia, Arpa, ARTTolkit, Aurasma, Blippar, Designers artoolkit, Layar, Vuforia y Wikitude.
